Polymer sefa yekunyungudika

Mukugadzira ma spunbonded nonwovens, kuitira kuti ive nechokwadi chekufambira mberi kwakanaka kwekutenderera uye kuderedza kuitika kwemafilaments akatyoka uye kudonha, seti mbiri dzemidziyo yekusefa inowanzoiswa. Sefa yekutanga (rough filter) yakaiswa pakati pescruder extruder uye metering pump, uye basa rayo guru nderokusefa kunze tsvina yakakura, kuitira kuti iwedzere nguva yekushandisa yechipiri sefa mudziyo uye kudzivirira metering pombi uye inotenderera pombi. , Kuwedzera kumanikidzwa kwemashure kweiyo extruder, nekudaro kunobatsira pakupedza uye plasticization yezvinhu panguva yekumanikidza. Yechipiri sefa (yakanaka firita) yakaiswa mumusangano wekutenderera, uye basa rayo guru nderokusefa tsvina yakanaka, makristasi mapoinzi, nezvimwewo, kudzivirira kuvhara kwespinneret, kuve nechokwadi chekufambira mberi kwakanaka kwekutenderera, uye kuvandudza kunaka kwefiber. Chimiro chesefa chidzitiro chinoenderana nechimiro uye saizi yespinneret, uye kazhinji iri multilayer rectangular sefa.
